SOAP COOLER AN D COMPRESSOR.

To all whom it may concern:

Be it known that I, Josnrn Boon, $11., a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Soap Coolers and Compressors, of which the following is a full, clear, and exact descripto the accompanying drawings, forming part of this specification.

My'invention has relation to machines for the purpose of coolin and compressing soap in one operation, an turning it out of the machine in bars of the proper cross-sectional area to be cut or stamped into hand cakes of soap.

It has as its object the providing of a cylinder wherein the soap when in liquid condition from the crutcher is to be poured, pressure devices automatically controlled to put the soap under pressure while in the cylinder, and a progressive cooling system whereby the soap during its progress through the cylinder under pressure will be gradually cooled down, and finally fpressed a long mentioned. It will be understood that the soap is very hot when it comes from the crutcher, but that it should not be brought at once into contact with a very cold dium. To be properly compressed and ready to cut into cakes, however, it must contain none of the heat of the saponification process. Ordinarily the soap from a crutcher is formed up into a large block and this is allowed to cool and dry out for a considerable length of time, with a consequent loss in manufacturing efiiciency. My new machine is designed to accomplish this operation of cooling, and compressing and cutting in a comparativel short time and without the necessity of ii large blocks of soap.

The objects detailed I certain construction and arrangement of parts to be hereinafter. more specifically pointed out and claimed.

In the drawings, Figure ;1 is a front elevation of the machine. Y I

Application filed December 17, 1915. Serial No. 67,852.

The cylinder 1, preferably supported vertically on standards 2, 2, has an inlet funnel 3 through which the soap from the crutcher (not shown) is poured. Mounted at the upper end of large supportin arms 4., 4, bolted to the upper end of the cy inder is a thrust bearing 5, which forms a bearing for an in teriorly screwthreaded sleeve 6. On this sleeve at the base is a worm gear 7, which is in mesh with a worm gear 8 on the shaft of a motor 9. This motor is mounted on the bracket lOwhich is secured in any desired manner to the supporting arms.

Mounted so as to reciprocate in the cylinder is a piston 11, that serves to compress the soap and force it out of the other end of'the cylinder as will be described. The piston is attached to a long shaft 12, that is screwthreaded and passes through the sleeve 6. A proper stuffing box 14 bolted to the end of the cylinder receives the shaft 12 which has a long key 13 that slides in a feather in the box, so that the shaft can slide but cannot turn in the said box. When the motor is running, therefore, the sleeve 6 will cause the shaft 12 to move slowly and with great pressure downwardly or upwardly, forcing the piston down into the cylinder and properly compressing the contents thereof.

A series of separate jackets are rovided along the length of the cylinder, a apted to receive cooling water and brine of progressively varying degrees of coldness. The topmost water jacket 16, having the inlet 17 and the outlet 18, is to be used with cold water as it comes from the usual outside water supply. The jacket 19 having the into deliver the soapv on a horizontal plane.

The section of the nozzle is water jacketed at 26, and is supplied with brineat, say,

twenty two degrees Fahrenheit, through the inlet and outlet 27, 28, respectively.

There are two sections of the nozzle between which is the die plate 29 which is of a size to be inserted in a slot 30 formed between the two sections. All the soap forced through the cylinder is pressed out through this die plate, which has, say, three apertures 31, of the desired cross-sectional area. The soap from the die plate passes out through the end section 32 of the nozzle which forms a wide, shallow passageway of the correct thickness for the bars of soap formed in the die, and is bolted onto the other portion of the nozzle and formed as is the other nozzle section so as to leave the char e of coole slot 30 above referred to. This extended end of the nozzle is waterjacketed at 33 and brine is sent through the jacket, through an inlet and an outlet 34 and 35 respectively, at a temperature of about seventeen degrees Fahrenheit.

At the beginning of an operation the cylinder is filled with soap, say, about one thousand pounds, or as much as a crutcher will hold, and the brine started gradually through the jackets, at the same time starting the motor. At the delivery end of the nozzle is an endless belt support 36 of a cutting machine on whichthe soap is delivered of the desired length, say, four feet. As

soon as four feet of soap has been forced out over the belt of the cutting machine, which;

will move as the soap is forced out onto it, the soap will come in contact with a'circuit breaking switch contact member 37, which will be pushed over by the soap, and held there until the pusher 38 of the cutter pushes the soap past the usual cutting wires and ofl? of the belt and returns to its normal position, the usher itself holding the breaker open. The reaker switch then automatically closes and the motor'continues to push out soap and the pusher is operated untilthe pistongets well down in the cylinder.

The piston will force about two-thirds of the contents out of the cylinder, leaving onethird in the base of the cylinder and the nozzle portions. When it has reached this point, the iston screw throws a switch 39 that cuts off t e current from the motor., The motor is then reversed, the piston raised and another charge put in. The cylinder is-large enough to hold the charge of a crutcher in addition to the amount in the c linder base and :the,

nozzle portions. Accor in ly after the operation 1s begun there wi be. a constant d and compressed soap in the nozz e, and there will never be such a rapid cooling of the u per portions of the soap mass, to revent t e even ap lication of pressure in t e base of the hardening. v 1 H By the dieplate, the soap will hie-formed into long bars of the correct cross-section and delivered out onto the table iorendless belt, where it will shut off the motor from time to time. This pro essive movement of the soap takes aconslderable time, referably fifteen minutes for a crutcher 'ful which is requisite for best results, andit can readily be-seen that the adjustment of the length of cylin or by premature eter, and a great dealof work can be turned out by it in a time comparatively Very short as compared with the processes now in common use. Various modifications might well be made without departing from the spirit of my invention, and I desire in the claims that follow to include the full range of equivalent structures for the elements set forth, although for the sake of brevit no attempt has been made to set out equiva ents while describing the invention in detail.

The time of operation is to be proportioned to the time that it takes-for the preparation of a crutcher of sea Two-thirds ap roximatelyof each crutc erfull will be -de ivered and cut at each operation, and the machine will take" a crutcherfull at each charge. 7
